I don't know how this survey is done. I can understand asking only players that have been traded to a team(then your sample size is too small)...that have maybe played for a few other teams. How else do you have a frame of reference for comparison as a player?
Players that have only played for the Steelers can only compare things like playing surface, stadium locker rooms, etc. If they are allowed to participate on all the questions how can they compare things like ownership? It's idiotic...do they answer according to what a recently traded player told them about owner X on team Y?....lol.
